We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. Send photos from Downpatrick (BT30) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Several misted or cracked units
- Repeated leaks after previous repairs
- Single-glazed or very poor thermal performance
Common causes we find
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
Roof lanterns in Downpatrick
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Downpatrick is around 27 miles from Newry, and both are within our County Down coverage.

What should you expect to pay in Downpatrick?
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc VAT), supplied and fitted. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Northern Ireland?
In Northern Ireland, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations (Northern Ireland) 2012, so we set out the route in writing first. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.

Roof lantern replacement in Downpatrick: questions
Do you need to visit to price roof lantern replacement?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Can you repair a lantern someone else installed in Downpatrick?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Can the new lantern use the existing opening?
Usually, if the kerb is sound and the size suits a standard or made-to-measure lantern.
Will you tell me if repair is enough?
Yes. We'd rather do a repair that works than sell a lantern you don't need.
